Google certainly cannot crawl your site 'pages' because there are none.

The best you can do is use Google's site submission process to submit your site. However, again, when the Google spider goes to crawl it there'll be nothing. That's why I would never create a whole site in Director... well, that's one of the reasons and pretty good one if all you need is one. I would use Director as I would Flash to add interactive/animated content to a website such as a "featured" section on the site - and even this can now be done using HTML5 and other scripting or cross browser frameworks/technologies such as JQuery which, IMHO, are much better solutions.

Ofcourse, with a small description-text of the dcr-content containing the most important keywords. You can use a frame-image as html- background. You can embed a movie directly, a small one perhaps, from which you can go to a greater stage later....

Yes, the search-engines control whether the keywords are really representative for the content of the html-side. So if you don´t want to inform the user of the dcr-content in advance with an overview, you may hide the text (white textcolor etc.).

(I find it helpful to get a hint of what the movie is about instead of having to scroll through and wasting time in case the content is not interesting for me - often the title alone is not precise enough. Compare the movies with a comment and without one at youtube, vimeo etc. You see that for many people the keywords in the title of the movie-file suffice.)

If it becomes necessary for the search engine to enter my data (biography, etc..) on the first page (html) become repetitive because they are also present in the DCR section. So I would need, if the data must appear in the html page, to make them invisible. At this point there is a possibility to make the text invisible (transparent?) in the first html page, over a background which is not uniform?

In my opinion two or three keywords might suffice: your name and s.th. like "biography" or "portfolio" (if you want that the whole world can find your biography with your name) not your actual biographical data itself.

Don´t know how many browsers can set text to transparent meanwihle. "Hidden" is also hidden for search engines.
